To all whom it mail concern:

Be it known that I, JOHN R. MGCREADY, a citizen of the United States,residing at Duncansville, in the county of Blair, State of Pennsylvania,have invented certain new and useful Improvements in Railway-Ties; and Ido hereby declare the following tobe a full, clear, and exactdescription of the invention, such as'will enable others skilled in theart to which it appertains to make and use the same.

This invention is an improvement in railway ties and has for one of itsobjects the provision of a tie principally made of metal and havingyieldable cushioning means for the rail which means'may be readilyremoved and replaced when worn out without removing the rail.

Another object is the provision of a railway tie of this. characterwhich is simple in construction, easy to manufacture and effective incarrying out the purpose for which it is designed.

The inventive idea involved is capable of receiving a variety ofmechanical expressions, some of which, for the purpose of illustratingthe present invention, are shown in the accompanying drawing, whereinFigure 1 is a side elevation of one form of a railway tie constructed inaccordance with the invention.

Fig. 2'is a top plan view thereof.

Fig. 3 is a longitudinal section.

Fig. 4 is a transverse section on theline 4:4 of Fig. 2.

Fig. 5 is a perspective view of another form of a tie.

Fig. 6 is longitudinal sectional view thereof.

Referringto the drawing and more particularly to 1 to 4 inclusive, thenumoral 10 indicates the base of a tie which extends transversely of therails and is provided upon its inner end with the lugs 11 which areadapted to be secured to similar lugs formed upon the base of theopposite tie. From this construction. it will be apparent that any oneof the ties may be detached from the one to which it is secured in orderto replace the same, when necessary.

The base 10 of each tie is preferably of rectangular form and has formedupon each longitudinal edge adjacent the outer end thereof anenlargement 12 including an in clined portion 13 having the triangularopening 14: beneath the same. The top 15 of Specification of LettersPatent.

each enlargement 12 is provided with a chamber 16 having an angularshoulder 17 intermediate the top: and bottom thereof. Gom-municcatingwith the chamber 16 on the outer side of the tie is an opening 18normally closed by means of a door 19, said open ig being adapted toreceive a relatively yiele :ble block 20, formed of any suitablematerial, such as wood, whicln-when in position, is seated in the bottomof the chamber 16 and is of a greater thickness than the distancebetween the bottom of said chamber and the plane ofthe shoulder 17 so asto compensate for wear upon the upper surface of said block. Seated inthe chamber 16 and upon the top of said block 20 is a metallic railsupporting plate 21 having the rail 22 secured thereto in any preferredmanner and also having its uppermost portion extending above the top ofthe enlargement 12. Through continued use it will be apparent that theupper surface of the block 20 will be gradually worn away and the plate21 will .recede into the chamber 16 until the bottom surface thereofcontacts the shoulder 17, thus limiting the downward movement of saidplate and at this time it is desirable to replace the block 20. Thisoperation may be readily and quickly performed by jacking the rail andremoving the door or closure 19 and then extracting the old block 20from the chamber 17 and through the opening 18, after which a new blockmay be inserted and the closure 19 again replaced.

Referring now to Figs. 5 and 6, it will be seen that the tie in thisinstance comprises a base 23 having the lugs 24 at its innor end adaptedto be secured to similar lugs upon the base of an adjacent tie andhaving formed upon its outer transverse edge the enlargement 25including the inclined portion 26. The top of the enlargement isprovided with a chamber 27 having an angular shoulder 28 therein, saidchamber communieating with an opening 29 which is normally closed by adoor 30, supported upon the outer end of the enlargement 25. Heavy coilsprings 31 are seated at the bottom of the chamber 27 and their upperends normally extend above the shoulder 28 and engage the bottom surfaceof a rail supporting plate 32 and yieldably support the same in positionin the chamber 27, the downward. movement of said plate being limited bythe shoulder 28. It will also be apparent from this description, thatwhen necessary the coil springs 31 may be removed and replaced throughthe opening-29. I

What is claimed is a 1. A railway tie comprising a base havin anenlargement formed thereon provide with a chamber in the top there-of,an angular shoulder in said chamber, a yieldable element seated in saidchamber and having its upper surface extending above said shoulder, anda rail. supporting plate mounted upon the top of said yieldable element.

' 2. A railway tie comprising a base having an enlargement formedthereon provided with a chamber'in the top thereof and an openingcommunicating with said chamber andwith: one side of said enlargement, a

shoulder in said chamber, a yieldable element insertible through saidopening into the bottom o'i": said chamber and having its upper endextending above said shoulder, and a rail supporting plate mounted uponthe upper end of said yieldable element.

(lopiesofthis patent may be obtained for 3. A railway tie comprising abase having an enlargement formed thereon provided with a chamber in thetop thereof and an opening communicating with said chamber and with oneside of said enlargement, a yieldable element insertible through saidopening into the bottom of said chamber, and arail supporting platemounted upon said yieldable element.

4. A railway tie comprising a base having an enlargement extending fromeach longitudinal edge thereof, each enlargement having a chamber, ayieldable element mounted in the bottom of said chamber, and a railsupporting plate supported by said yieldable element."

In testimony whereof, I affix my signature, in the presence of twowitnesses.
